I've made a Visio drawing to calculate the diffraction of laser beam through a diffraction grating.
I checked my calculation making a handmade spectrometer using diffraction grating sheet.
I think I've had a better comprehension more than that I can gain from a text book.
Likely the macro doesn't work in V2007, but I get the idea.
(I've done a lot of IR, UV-VIS, and NMR spectroscopy)

I always like your projects - they are ambitious, creative and intellectually challenging.
Thank you.
I think the macro works in Visio 2007.
This macro works only to convert wave length to RGB.
